When a CA small claims judgment is set for a specific amount, can the party who won tack on more fees later?

My question is when a small claims judgment is set for a specific amount, can later on the party who won the judgment tack on 2500.00 more due for fee’s, etc…?

If you have an owed balance upon moving out of a rental property and the property mgmt files a small claims case for a specific amount (ex. 2000.00) which includes what you owe plus attorney fee’s and the court orders a judgment against you for that amount….. Then a collection agency gets a hold of your account to collect and they state that your owed balance is way more than what was originally filed (ex. 4500.00) is that legal?

I understand that an additional amount would be due for interest or agency fee’s but 2500.00 more is not close to being accurate for interest of agency fee’s…..
